Ramdomize the blocks while selecting a specific selection for a block in real time

[Zh Wu]

I am designing an experiment with two blocks, BlockA and BlockB. 

I want 1/4 of participants to do BlockA randomly and then BlockB 
sequentially, 1/4 of participants to do BlockA sequentially and then BlockB 
randomly, 1/4 of participants to do BlockB randomly and then BlockA 
sequentially, and 1/4 of participants to do BlockB sequentially and then 
BlockA randomly. 

I know how to select the blocks randomly (i.e., half participants do BlockA 
first and the other half BlockB first), but for the specific list, I don't 
know how to change the selection for a specific participant.

Any help would be greatly appreciated!
